Given numbers are 803, 620, 687

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(803, 620) = 497860

GCD(803, 620) = ( 803 x 620 ) / 497860

= 803 / 620

= 803

Step2:

LCM(1, 687) = 687

GCD(1, 687) = ( 1 x 687 ) / 687

= 1 / 687

= 1

So, Greatest Common Divisor of 803, 620, 687 is 1
